DH is about 3/4 stone overweight with T2 diabetes. He's going on an extreme weight loss diet as part of a trial for 3 months to see if losing weight quickly can 'reset' things (at least, I think that's the science behind it) starting in a fortnight's time. He'll be on shakes for the 12 weeks and regularly monitored/supported - rather him than me, but he is absolutely determined which I admire massively.
I'd like to support and encourage him all I can from the start until finish. Anyone got any ideas on how I can do that?
